MacBook Air or an HP Envy? please help me out!?

So I'm going to collegeand I need my first laptop. I like to game bit idk if I will have time. So I like the Macbook Air because its so light weight, the very solid hardware and I like the OS(operating system). I like that the MacBok Air could last me 10 years. But the HP Envy I like too, because I can do some gaming in it and I love the beats audio. Another huge reason I like it is because of the significantly cheaper price at around $750 compared to the $999 Air my parents will pay for half of a laptop for my graduation.what do you think and why?
